The passage of a strong cold front overnight may produce severe weather over southwest WA.
A strong cold front is approaching from the west and will move through southwest WA from late Monday into early Tuesday.
Damaging winds, averaging 60 to 70 km/h with peak gusts to around 100 km/h are possible and could cause damage to homes and properties. Damaging winds are expected to develop about the Southwest Capes after 8pm Monday evening, extending throughout the warning area, including the Perth Metropolitan area, by around 11pm. Conditions will ease during Tuesday morning although squally thunderstorms and small hail may persist until early Tuesday afternoon southwest of a line from Bunbury to Bremer Bay.
Locally dangerous winds, averaging 80 to 90 km/h with peak gusts in excess of 125 km/h are possible with the passage of the front, southwest of a line from Mandurah to Walpole, and could cause significant damage or destruction to homes and property in localised areas.
Heavy rainfall is possible in the Lower West and South West Districts.
Tides will be higher than expected between Kalbarri and Albany, particularly during Tuesday morning.
Damaging surf conditions are likely which could cause beach erosion between Bunbury and Walpole on Tuesday.
Locations which may be affected include Bunbury, Busselton, Mandurah, Manjimup, Margaret River, Perth, Augusta, Dunsborough, Harvey, Lancelin, Walpole and Yanchep.
This is typical weather for this time of the year but winds and rain may cause damage to property and make road conditions hazardous.
The Department of Fire and Emergency Services advises that people should:
* If outside find safe shelter away from trees, power lines, storm water drains and streams.
* Close your curtains and blinds, and stay inside away from windows.
* Unplug electrical appliances and do not use land line telephones if there is lightning.
* If boating, swimming or surfing leave the water.
* Be alert and watch for hazards on the road such as fallen power lines and loose debris.
* Keep away from flooded drains, rivers, streams and waterways.
* Be careful of fallen trees, damaged buildings and debris.
* Be careful of fallen power lines. They are dangerous and should always be treated as live.
* Assess your home, car and property for damage.
* If damage has occurred take photos and contact your insurance company to organise permanent repairs.
* If your home or property has significant damage, like a badly damaged roof or flooding, call the SES on 132 500.
